I went to Viking Saab in Watford (UK) at lunchtime to have the wheel alignment set on my Aero and one of the guys had just delivered an Abbotted 9000 Aero that they'd had in for some work. It had just had uprated brakes fitted (perhaps that's what it was doing at Viking?)

Apparently, it has a highly-tuned Abbott ECU, the brakes, suspension and possibly an LSD?
